A: AC or our line voltage is sinusoidal in nature it goes up to a positive peak returns to zero and proceed to the negative peak. 120V AC is actually swinging from peak to peak. It is 120 volts but the peak is the 120 v times 1.41 or 169.2 volts and since it also go negative then the peak to peak 120 volts times 2.82 or 338.40 volts or twice the peak voltage
Unless otherwise specified, a.c. voltages (U) and currents (I) are always expressed in root-mean-square (rms) values. For a sinusoidal waveform, the relationship ship between the rms value and the peak value is as follows:
(Upeak = Urms/0.707) and (Ipeak = Irms/0.707)
Conversions of RMS voltage, peak voltage and peak-to-peak voltage. Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".
The root-mean-square value of a sinusoidal waveform is 0.707 times the peak value. So, you need to halve the peak-to-peak value, then multiply it by 0.707.
The nunber is 2.82 or 1.41 for peak
A: Practically all of the bridges used to find the value of passive components uses a null signal to determine the value In reality null means the lack of a signal where it is virtually eliminated when that occurs that is the null or no signal.
to calculate and measure the impedance ,admittance is simple
what is the diference betwean calculated and maesured value
char a = 'A'; System.out.println((int)a);
1. Digital Signal is non-continuous signal where as analog is continuous signal 2. Digital signal contain only two value that is 0 or 1,or high or low where as analog contain all the values in it's time interval 3.Chance of attenuation in analog is more then digital signal
Calculate the capacity of a telephone channel of 3000hz and signal to noise ratio of 3162?
It can be calculated by simplifying the ratio between power of signal by power of noise
How do you calculate the actual cash value of a home
there is no value. its baseball.
The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.
If the AC signal is sinusoidal, then the RMS value is 141 divided by square root of 2, i.e. 99.7 volts.
A: Practically all of the bridges used to find the value of passive components uses a null signal to determine the value In reality null means the lack of a signal where it is virtually eliminated when that occurs that is the null or no signal.
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com
signal value changes with time
In the name of Allah,the most Gracious,the most Merciful... The Oscilloscope has several advantages over a voltmeter, for example if you want to determine a signal parameters [ voltage values (max,peak-to-peak,rms,average...etc),frequency,offset...etc ] using measurement tools: 1- You can use the Oscilloscope whatever the signal frequency is, but you can't use the Avometer unless the signal frequency is 50 to 60 Hz. 2- The Oscilloscope shows you the shape (form) of the signal, while the Avometer doesn't. 3- You can determine the maximum value of the signal (max voltage) and peak-to-peak voltage when you observe the signal on an Oscilloscope,hence you can calculate the rms (root mean square) value, i.e. the effective value , the average value and the offset of signal form the time axis (the horizontal axis). While an Avometer can only give you the rms value.
